Core Data issue in iOS 7

Question

I have a problem between iOS 8 and iOS 7. I am using Core Data, I have an entity called Pessoa (NSManagedObject), only when doing a data update happens a EXC_BAD_ACCESS, only that, no other description or error more.

It happens in the following section:

let batchUpdateRequest = NSBatchUpdateRequest(entityName: "Company")

Strange because in the iOS 8 works normally and updates the data.

The code of the method is basically:

func update (people: People) {
        var error: NSErrorPointer = nil

        //O erro ocorre aqui
        let batchUpdateRequest       = NSBatchUpdateRequest(entityName: "People")

        batchUpdateRequest.predicate = NSPredicate(format: "idObject == \(people.idObject)")            
        batchUpdateRequest.propertiesToUpdate = [
            "name" : people.name,
            "phone" : people.phone,
            "address" : people.address,
            "email" : people.email
        ]
        batchUpdateRequest.resultType = NSBatchUpdateRequestResultType.UpdatedObjectsCountResultType
        let result = managedObjectContext?.executeRequest(batchUpdateRequest, error: error) as NSBatchUpdateResult
    }

I tried to change it to:

let batchUpdateRequest = NSBatchUpdateRequest(entityName: "Company" as NSString)

But all without success.

You won’t be able to use the NSBatchUpdateRequest in the iOS 7, because this was only introduced in the iOS 8. Reference: iOS 8.0 Diffs API

In iOS 7 what you have to do is iterate between the objects and make the changes one by one.
